The flash flood threat persists into the overnight hours before temporary dry conditions return.
A Flood Watch is in effect until 6 AM Sunday for Western Colorado and Eastern Utah. The greatest threat for flash flooding will occur overnight as a line of showers and thunderstorms associated with a cold front moves through the area, potentially dropping half an inch to an inch of rain in some spots.
The cold front will bring high temperatures down to the low to mid 60s on Sunday before warming up again.
